But not so often, like the kernel before.
I have send 8GByte data over SSH with rsync. No Systemcrash. But the messages in /var/log/messages are not fine.
In the past not more than 350MByte was successfull til systemcrash. It is much better, but why do I got this bad messages.

I use the Kernel 3.5.7-gentoo and the Kernel 3.7.6-vanilla. On both Kernel I got already the FIFO Problem like before with Kernel 2.6x!
My Powermac G4 hangs on Cisco Switch 2960G. So I fixed it by setting 'SPEED 100' on on Port where G4 hangs on!
The Problem I reported already exists.
